Sine filters with ACS800 drives

What this chapter contains

This chapter gives information on using sine filters with ACS800 single drives.

General

Sine filters are low-pass filters that suppress the high frequency components of the
drive output. The sine filters available for the ACS800 consist of single- or three-
phase reactors and delta- or star-connected capacitors.
The following diagram shows a drive system with a sine filter.
The sine filters are used in conjunction with the ACS800 Standard Application
Program. The Scalar motor control mode (instead of DTC mode) is used with a sine
filter.

Voltage drop

At a frequency of 50 Hz and nominal drive output current, the sine filter drive
decreases the output voltage as follows:
Nominal supply
voltage (V AC)
The voltage drop must be taken into account when dimensioning the motor and the
drive since decreasing the motor voltage will increase the current if the power is kept
at a constant level. At 60 Hz the voltage drop is approximately 20% higher.
